<p>Note that this operator is provided only for implementing generic
debug and inspection mechanisms.
The keys returned for certain handle types can change without notice.
Additionally, some handle types might not be supported by this operator.
Also, this operator is not optimized for performance.
To obtain more reliable information about a handle in a program, it is
strongly recommended to use 该算子s specialized for the particular
handle type, such as <a href="get_object_model_3d_params.html"><code><span data-if="hdevelop" style="display:inline">get_object_model_3d_params</span><span data-if="c" style="display:none">get_object_model_3d_params</span><span data-if="cpp" style="display:none">GetObjectModel3dParams</span><span data-if="com" style="display:none">GetObjectModel3dParams</span><span data-if="dotnet" style="display:none">GetObjectModel3dParams</span><span data-if="python" style="display:none">get_object_model_3d_params</span></code></a>,

<p>如果参数均有效，算子 <code><span data-if="hdevelop" style="display:inline">get_handle_tuple</span><span data-if="c" style="display:none">get_handle_tuple</span><span data-if="cpp" style="display:none">GetHandleTuple</span><span data-if="com" style="display:none">GetHandleTuple</span><span data-if="dotnet" style="display:none">GetHandleTuple</span><span data-if="python" style="display:none">get_handle_tuple</span></code>
返回值 <TT>2</TT> (
      <TT>H_MSG_TRUE</TT>)
    .
If the handle is invalid or does not support the given key, or if the
key references an iconic object instead of a tuple, an exception is raised.
